The valve spring is shortened after a long period of use, indicating that the fatigue deformation has occurred, and the accident of fracture damage is easy to be used. In addition, the spring becomes shorter, the elasticity drops, the valve will be closed lax or even cause the work of the valve hit the piston caused by mechanical damage accident. Therefore, the maintenance should pay attention to timely check the measurement valve spring height, timely replacement of the length of the valve spring.Air Cooled Diesel Engine

The piston should be installed with a clamp with a limit block to limit the opening limit of the piston ring. If there is no special installation pliers, you can install it with your bare hands.Air Cooled Diesel Engine

But the manual installation is more laborious, easy to card injury finger; with hand break piston ring, open size is not easy to control, breaking the mouth too big easy to break the piston ring, even if the piston is not broken but will also be damaged, ambush the danger of rupture. Theoretically, when the piston opening size is larger than 8 times times the thickness of the piston ring, the piston ring has the possibility of breaking or opening the shape.Air Cooled Diesel Engine

Therefore, when the lack of special tools to install the piston ring unarmed, should also be properly mastered the opening of the piston ring, do not make it too large. Before the piston ring is not installed should not be free to close the opening Test ring, this will also cause the piston to deform or break.Air Cooled Diesel Engine

Some maintenance in the use of sealant, will be squeezed to the sealing surface, and then with the fingers or to stick the glue Shiping on the sealing surface, this approach is not correct. Because the squeeze out of the plastic beam shape, the machine can be more effective to form a gap seal, and will be able to wipe the plastic beam after the sealing quality will damage the seal.Air Cooled Diesel Engine

When the two-tooth belt is used, it is necessary to maintain the balance of two tapes, and the transmission is stable, so that the two tapes often maintain the same structure, size and shape. In general, the new toothed tape is more than two pairs of packaging, the high meter requires two new tooth-shaped tape length difference of not more than 2mm.Air Cooled Diesel Engine
